curves; and the invention consists in cer-' tain novel constructions andcombinations of parts as will be hereinafter described and claimed.

In the drawing Fi ure 1 is a top plan view of a portion, 0 an automobileprovided with my improvements. Fig. 2 is a detail plan View, partlybroken away, of the master wheel and the parts immediately associatedtherewith. Fig. 3 is a vertical longitudinal section drawn through thebracket and the master wheel carried thereby. Fig. 4: is a detail viewof the rocking arm for operating the master wheel. Fig. 5 is a detailside view of a lamp in place on the frame of a machine.

In practice, the lamps A which may be of any suitabletype, are mountedon the frame B above the spring C, see Figs. 1 and 5, in such manner asto prevent the road shocks from influencing the'lam s. As shown, one ofthese lamps is pivot vertically at A,

see Fig. 5, so it may be turned on 1ts vertical axis and is providedwith a sprocket wheel D receiving a sprocket chain E which connects thepinion D with the master wheel F so the turning of the latter willeffect a corresponding movement of the lamp, the

inion D being much smaller than the wheel F so that the multiplying gearwill give the desired radius of action to the lamp. The other lamp maybe similarly connected to the steering -mechanism.

The sprocket wheel F meshes with the chain E and is provided with arounded notch F entered by a roller G of the detent G, the roller Gbeing spring pressed by the spring Gr into the notch F in such manner asto hold the wheel F normally in osition as against accidental movementan at the same time permit the convenient turning of the wheel F whenforce is applied thereto by the action of the steering gear as morefully described hereinafter.

bination, a pivotally supported lam The wheel F is journaled at F in thebracket H, suitably secured at H to the car and the rocking arm I ispivoted concentrically. with the wheel F and is connected at itsswinging end I by a link J with the steering gear of the car,-see Fig.1, so that the movement of the steering gear will rock the arm or leverI in such manner as to cause it to rock the master Wheel F when themachine is rounding curves. The lever I is capable of a limited rockingmovement independently of the master wheel, so that the steering gearcan be moved slightly as in ordinary steering on straight roads withoutwavering the lamps from a straight ahead position. To this-end, a pin Ion the lever I operates in a slot F in the wheel F so the lever I has aslight play from its normal position as shown in Fig. 2, in bothdirections without moving the wheel F.

I have'shown theimprovement applied to only one lamp in Fig 1, but mamestly it may be applied to both'lamps, if desired.

The detent G as before described, is a yielding detent operating" tohold the wheel F yieldmgly in normal position withoutpreventing theforcible movement of the said wheel in either direction'according to themotion given to thesteering ear.

In operation, it will be noticed that'if the steering gear is operatedto turn the ma chine in one direction or the other, the lamp will becorrespondingly turned to throw the light in the direction of the curve.

I claim:

1. A lamp attachment, comprising in comprovided with a pinion, a masterwhee relatively larger tian the pinion and provided with a roundednotch, a yielding sprin 'actuated detent operating in said notch to holdthe master wheel yieldingly in normal position, a sprocket chainconnecting the master wheel with the pinion, a rocking lever swingingconcentrically with the master whee and provided with a pin, the masterwheel having a slot receiving said pin, steering gear and connectionsbetween the rocking lever and the steering gear.

2. An apparatus, comprising a vertically pivoted lamp provided with apinion, a master wheel geared with said plnion and provided with arounded notch and with a slot, a sprin actuated yielding detentoperating in sai notch and a lever adapted for connection with asteeringgear and rocking concentrically with the master Wheel andprovided with a pin entering the slot of the master Wheel.

3. The combination of a vertically pivoted lamp, a master Wheel gearedwith the lamp and provided with a slot, and a rockin lever for operatingsaid master gear, sai lever being adapted for connection with a steeringgear and being provided with a pin entering the slot of the masterWheel, substantially as set forth.

4. In a lamp attachment for automobiles,

the combination of a lamp and a master Wheel for operating the lamp, ayielding detent'for holding the master Wheel yieldingly 1 RUBERT S.MATHESUN.
